I have some if you fancy a trip to Aberdeen. Can't remember the grade, it's the grade Geoff Moss uses for making panels. Not home until the weekend. I'm also off to Clola on Saturday probably to pick up some welding gas if that is easier for you?
^^^ WHS ^^^^ as non of the lower tailgate is aluminium I would not introduce yet another steel / aluminium 'battery' there are plenty on the original car.I'd consider galvanised sheet steel instead of aluminium as less change to electrolytic corrosion in the future

My thinking was to remove the existing rusty skin, treat the frame to a good rust treatment followed by an epoxy coating then where the alloy contacts to apply a layer of adhesive tape to provide a layer between the alloy and the steel followed by a spray of wax on the internals. Does this sound like it would work?
A bit off topic: The original 'Birmabright' is thought by some to be close to 5052 and can be used to repair the original panels on Landies.If it hasn't too much shape in it I would go for 5052. Harder to work but less prone to dent.
3003 is a common alloy for car panels too, but I can't find it here so 1050 or 5052 is my choice.
The epoxy would help and the adhesive tape plus wax is putting way more effort into it than Rover ever did. I re made mine with zintec twenty odd years ago, it needs re doing now but will probably be replaced by the later ( four door) lower and all the strikers that I have stashed away.
